feat(skills): add CCW orchestrator and refactor command-guide to ccw-help

CCW Skill (new):
- Stateless workflow orchestrator with intent classification
- 6 workflow combinations: rapid, full, coupled, bugfix, issue, ui
- External configuration: intent-rules.json, workflow-chains.json
- Implicit CLI tool injection (Gemini/Qwen/Codex)
- TODO tracking integration for workflow progress

CCW-Help Skill (refactored from command-guide):
- Renamed command-guide → ccw-help
- Removed reference folder duplication
- Source paths now relative from index/ (../../../commands/...)
- Added all-agents.json index
- Simplified SKILL.md following CCW pattern

+# Review-Fix Workflow Action
+
+## Pattern
+```
+review-session-cycle → review-fix
+```
+
+## Trigger Conditions
+
+- 关键词: "review", "审查", "检查代码", "code review", "质量检查"
+- 场景: PR审查、代码质量提升、安全审计
+
+## Execution Flow
+
+```mermaid
+graph TD
+    A[User Input] --> B[review-session-cycle]
+    B --> C{7维度分析}
+    C --> D[Security]
+    C --> E[Performance]
+    C --> F[Maintainability]
+    C --> G[Architecture]
+    C --> H[Code Style]
+    C --> I[Test Coverage]
+    C --> J[Documentation]
+    D & E & F & G & H & I & J --> K[Findings Aggregation]
+    K --> L{Quality Gate}
+    L -->|Pass| M[Report Only]
+    L -->|Fail| N[review-fix]
+    N --> O[Auto Fix]
+    O --> P[Re-verify]
+```
+
+## Configuration
+
+| 参数 | 默认值 | 说明 |
+|------|--------|------|
+| dimensions | all | 审查维度(security,performance,etc.) |
+| quality_gate | 80 | 质量门槛分数 |
+| auto_fix | true | 自动修复发现的问题 |
+| severity_threshold | medium | 最低关注级别 |
+
+## CLI Integration
+
+| 阶段 | CLI Hint | 用途 |
+|------|----------|------|
+| review-session-cycle | `gemini --mode analysis` | 多维度深度分析 |
+| review-fix | `codex --mode write` | 自动修复问题 |
+
+## Slash Commands
+
+```bash
+/workflow:review-session-cycle  # 会话级代码审查
+/workflow:review-module-cycle   # 模块级代码审查
+/workflow:review-fix            # 自动修复审查发现
+/workflow:review --type security  # 专项安全审查
+```
+
+## Review Dimensions
+
+| 维度 | 检查点 |
+|------|--------|
+| Security | 注入、XSS、敏感数据暴露 |
+| Performance | N+1查询、内存泄漏、算法复杂度 |
+| Maintainability | 代码重复、复杂度、命名 |
+| Architecture | 依赖方向、层级违规、耦合度 |
+| Code Style | 格式、约定、一致性 |
+| Test Coverage | 覆盖率、边界用例 |
+| Documentation | 注释、API文档、README |
+
+## When to Use
+
+- PR合并前审查
+- 重构后质量验证
+- 安全合规审计
+- 技术债务评估
+
+## Risk Assessment
+
+| 风险 | 缓解措施 |
+|------|----------|
+| 误报过多 | severity_threshold过滤 |
+| 修复引入新问题 | re-verify循环 |
+| 审查不全面 | 7维度覆盖 |
